Not that I would expect a whole host of people. This is just a list of what I think could be possible and what I'd like to see. If given the choice I'd probably just restrict it to a few that generally served the story (not counting blink and you miss it background cameos).
Tony Stark/Iron Man. He's one of the most important characters as well as a scientific genius akin to Peter Parker, plus depending on if/how he interacts with Peter/Spidey in Civil War.
Steve Rogers/Captain America. Like Iron Man he's one of the most important characters and depending on his possible interaction in Civil War.
Kingpin. I would like to see a bit of world building. Short cameo or even a reference. One of Spidey's most memorable villains. Perhaps Spidey could stop some low level thugs connected to Kingpin?
Coulson & Nick Fury. A SHIELD presence isn't the same thing it was in Iron Man 1 due to events of Winter Soldier, but it's possible Coulson could be interested in monitoring meta-humans.
Fitz & Simmons (with SHIELD). I think it would be funny to see Peter Parker with Fitz & Simmons just geeking out together.
Matt Murdoch/Daredevil. Maybe just a brief cameo as Matt. Perhaps on tv speaking in defence of a client.
Bruce Banner/Hulk. It would be nice to see Peter Parker meet Banner and idolise him for his scientific work.
Stark cameo. Tony and Norman having a go at each other.
Iron Patriot FTW.
Also I wouldn't mind seeing JJJ ranting about Avengers, Daredevil etc as well as Spider-man. It would be cool if we could see J.K. Simmons as JJJ cameoing around in other MCU properties too.
Similarly if Daredevil were to get a season 2 then I wouldn't mind a crossover with Spider-man taking on the Kingpin. Though a Spider-man/Daredevil film with Kingpin as the villain could make a good sequel too.
I could see Quicksilver having the Human Torch role. Maybe Scarlet Witch too.
I have trouble picturing that. I don't see much parity between Quicksilver or Scarlet Witch and Johnny Storm. I think if they were to go a bit random then Sky/Quake could fit that bill a bit more naturally as the superhero best friend.
